Multinational companies assign expatriates to bridge the scarcity of employees with innovative behaviour from the local labour market. Despite expatriates' significant role in inducing innovative ideas for multinational companies, the existing literature has scarcely examined those antecedent factors that affect their innovative behaviour. Even though previous studies indicated the determinant impact of host countries' culture on the expatriates' work-related behaviour, little is known about how far it affects their innovative behaviour. Therefore, drawing on the personenvironment fit theory, this study examines the impact of personal value orientation and the host country's culture alignment on expatriates' innovative behaviour. The study covers 149 expatriates, from nine countries, who work in the high-tech industrial zone of Shenzhen, South China's industrial hub. Moreover, it applies a structural equation model using Amos TM 23 to conduct the analysis. The results reveal that personal value orientation fit with the host country's national culture has a significant impact on expatriates' innovative behaviour. Cross-cultural adjustment level is found to mediate this relationship. Theoretical and practical implications are discussed, and suggestions for future research are drawn from the study's limitations.

Wastewater surveillance systems have become an important component of COVID-19 outbreak monitoring in high-income settings. However, its use in most low-income settings has not been well-studied. This study assessed the feasibility and utility of wastewater surveillance system to monitor SARS-CoV-2 RNA in Addis Ababa, Ethiopia. The study was conducted at nine Membrane Bio-reactor (MBR) wastewater processing plants. The samples were collected in two separate time series. Wastewater samples and known leftover RT-PCR tested nasopharyngeal swabs were processed using two extraction protocols with different sample conditions. SARS-CoV-2 wastewater RT-PCR testing was conducted using RIDA GENE SARS-CoV-2 RUO protocol for wastewater SARS-CoV-2 RNA testing. Wastewater SARS-CoV-2 RNA RT-PCR protocol adaptation, optimization, and detection were conducted in an Addis Ababa, Ethiopia context. Samples collected during the first time series, when the national COVID-19 case load was low, were all negative. Conversely, samples collected during the second time series were all positive, coinciding with the highest daily reported new cases of COVID-19 in Ethiopia. The wastewater-based SARS-CoV-2 surveillance approach is feasible for Addis Ababa. The COVID-19 wastewater based epidemiological approach can potentially fill the evidence gap in distribution and dynamics of COVID-19 in Ethiopia and other low-income settings.
